| nucleoside-diphosphate kinase | <enzyme> A phosphotransferase enzyme that is found in mitochondria and in the soluble cytoplasm of cells. It catalyses reversible reactions of a nucleoside triphosphate, e.g., ATP, with a nucleoside diphosphate, e.g., UDP, to form ADP and UTP. Many nucleoside diphosphates can act as acceptor, while many ribonucleoside triphosphates and deoxyribonucleoside triphosphates can act as a donor. Chemical name: ATP:nucleoside-diphosphate phosphotransferase Registry number: EC 2.7.4.6 (12 Dec 1998) |
|---|---|
| nucleoside diphosphate | The pyrophosphoric ester of a nucleoside, i.e., a nucleoside in which the H of one of the ribose hydroxyls (usually the 5') is replaced by a pyrophosphoric (diphosphoric) radical; e.g., adenosine 5'-diphosphate. Compare: nucleoside bisphosphate. (05 Mar 2000) |
| nucleoside-diphosphate sugars | Nucleoside diphosphates linked through the 5'-diphosphoric group with simple or complex carbohydrates; e.g., GDP-mannose, UDP-glucose (UDPG), dTDP-glucosamine. (05 Mar 2000) |
| pyrophosphate-nucleoside kinase | <enzyme> From acholeplasma laidlawii; phosphorylates adenosine, inosine, and guanosine to the corresponding mononucleotides Registry number: EC 2.7.1.- Synonym: ppi dependent nucleoside kinase (26 Jun 1999) |
| nucleoside-phosphate kinase | <enzyme> An enzyme that catalyses reversible reactions of a nucleoside triphosphate, e.g., ATP, with a nucleoside monophosphate, e.g., ump, to form ADP and udp. Many nucleoside monophosphates can act as acceptor while many ribo- and deoxyribonucleoside triphosphates can act as donor. Chemical name: ATP:nucleoside-phosphate phosphotransferase Registry number: EC 2.7.4.4 (12 Dec 1998) |
| nucleoside triphosphate-adenylate kinase | <enzyme> Other nucleoside triphosphates may replace GTP as substrate Registry number: EC 2.7.4.10 Synonym: GTP-AMP phosphotransferase, AMP-GTP phosphotransferase (26 Jun 1999) |
| MAP kinase kinase kinase | <enzyme> From pc12 cells; reactivates map kinase kinase inactivated by protein phosphatase 2a by phosphorylation of serine residues; tak1 (tgf-beta-activated kinase 1) is a member of the mapkkk family; genbank ab006787 (mouse) Registry number: EC 2.7.10.- Synonym: mapkkk, tak1 mapkkk, ask1 (kinase), apoptosis signal-regulating kinase 1 (26 Jun 1999) |
| uridine diphosphate kinase | <enzyme> Aspect of EC 2.7.4.6 Registry number: EC 2.7.4.- Synonym: udp kinase (26 Jun 1999) |
| cap II RNA(nucleoside-2'-)methyltransferase | <enzyme> Converts cap i-terminated mRNA to cap II-terminated mRNA Registry number: EC 2.1.1.- Synonym: cap II methylase (26 Jun 1999) |
| cap I RNA (nucleoside-2'-)methyltransferase | <enzyme> Converts cap 0-terminated mRNA to cap i-terminated mRNA Registry number: EC 2.1.1.- Synonym: cap I methylase (26 Jun 1999) |
| mRNA (nucleoside-O(2'))-methyltransferase | <enzyme> Catalyses the reaction of s-adenosyl-l-methionine and m(7)g(5')pppr-RNA to yield s-adenosyl-l-homocysteine and m(7)g(5')ppprm-RNA; mRNA containing an o(2')-methylpurine cap Registry number: EC 2.1.1.57 (26 Jun 1999) |
| purine-nucleoside phosphorylase | <enzyme> An enzyme that catalyses the reaction between a purine nucleoside and orthophosphate to form a free purine plus ribose-5-phosphate. Chemical name: Purine-nucleoside:orthophosphate ribosyltransferase Registry number: EC 2.4.2.1 (12 Dec 1998) |
| pyrimidine-nucleoside phosphorylase | <enzyme> Consider uridine phosphorylase and thymidine phosphorylase Registry number: EC 2.4.2.2 Synonym: pyrimidine nucleoside phosphorylase (26 Jun 1999) |
| nucleoside | <biochemistry> Purine or pyrimidine base linked glycosidically to ribose or deoxyribose, but lacking the phosphate residues that would make it a nucleotide. Ribonucleosides are adenosine, guanosine, cytidine and uridine. Deoxyribosides are deoxyadenosine, deoxyguanosine, deoxycytidine and deoxythymidine (the latter is almost universally referred to as thymidine). (18 Nov 1997) |
| nucleoside analogue | A synthetic molecule that resembles a naturally occuring nucleoside, but that lacks a bond site needed to link it to an adjacent nucleotide. (09 Oct 1997) |
